Flexible TPU Grommet for 3D Printer Enclosure – Cable or Filament Pass-Through

Need a clean and flexible pass-through for your 3D printer enclosure? This TPU grommet is designed to route filament or cables while maintaining a tight seal and reducing dust, noise, and fumes.

Ideal for use in DIY 3D printer enclosures (IKEA Lack, Creality, Elegoo, etc.), this grommet snaps into a standard hole and flexes enough for multiple cable sizes or filament tubes. It's easy to print and soft enough to prevent abrasion over time.

Ventilation duct seal assist

🛠 Features:

Prints in TPU (tested in 95A)

Snaps into a 40mm hole (or scale as needed)
